2 square meters of closed balcony, unexpectedly can grow 20 kinds of vegetables, one year is enough to eat!

The first step of growing vegetables is to use space.

The small balcony of 2 square meters, the first thing to think about is the use of space. All kinds of iron and wooden shelves are the basic tools for raising three-dimensional vegetables.

Specific operations:

Like the position near the window, good lighting, high utilization rate, set up two-layer wooden shelves, can be customized with anticorrosive wood boards, lined with tarpaulins, and planted with leeks, chili peppers and tomatoes. In order to prevent overheating in the direct sun next to the window, you can stick a reflective and heat insulating aluminum film on the surface next to the window.

Two rows of moving iron frames can be set on both sides of the balcony, and a row of shelves can be made into a single-layer hanging type, which can be used to plant climbing vine vegetables such as cucumbers, which can simulate the way of the greenhouse and use white thin thread as a traction rope to let the vines grow up along the rope. Multi-layer partition is made on the side of the shelf, which is used to place small potted plants and grow strawberries.

Another shelf can set up multi-layer hydroponic vegetables, using hydroponic pipe cultivation, planting some leafy vegetables, such as lettuce, hollow cabbage, chrysanthemum. Hydroponic leafy vegetables, crop after crop, clean and soilless, growing rapidly.

The second step of growing vegetables is lighting and ventilation.

The biggest problem with the closed balcony is that the sunlight exposure time is too short, as well as the very fatal ventilation problem.

Lighting:

Living in the building, a small balcony, want more than 10 hours of natural light a day can not be achieved, but in order to meet the growth needs of the plant, we can carry out artificial supplementary light. Install LED supplementary lights on each row of shelves to increase lighting.

Ventilation:

If the ventilation is not good, install the equipment and install two solar panels at the top of the window to connect the fans installed at both ends of the shelf to make the whole closed environment in a state of air flow, prevent the balcony from being too high in temperature and humidity, and easily cause diseases and insect pests.

The third step of growing vegetables, the trouble of diseases and insect pests

When growing vegetables on the balcony, what cannot be avoided is the breeding of diseases and insect pests. Some are bugs flying in from the outside, and some may be germs or eggs carried in the soil.

For the problem of diseases and insect pests, the most important thing is frequent observation, early detection and early treatment, removal of plants affected by diseases and insect pests, to prevent continued harm to other vegetables, in order to eliminate them in serious cases, a small amount of pesticides can be used.

If you don't want to use pesticides, we can catch insects manually, hang an insecticidal yellow board next to vegetables, or make your own chili water, choose especially hot chili peppers, boil them with water for half an hour, cool them and spray them on the surface of vegetables.
